They are boot loader executables, exist on UEFI Unified Extensible Firmware Interface based computer systems, and contain data on how the boot process should proceed.
It automates the process to repartition the hard disk for UEFI-enabled hardware. You can integrate the conversion tool into the in-place upgrade process to Windows Other modern operating systems can also use GPT. It may be stored in flash memory on the motherboard, or it may be loaded from a hard drive or network share at boot. Electronic fuel injection replaces the need for a carburetor that mixes and fuel.
UEFI also has more advanced security features such as secure startup, which helps to keep your computer more secure.

Given the complexity of modern operating systems, some of these boot-loaders tend to do multi-stage loading, where the main boot-loader loads the second-stage-boot-loader in an environment which is not restricted to bytes.
The boot-loader then loads the kernel into memory. In Windows, wininit. After all this, and after some other drivers are initialized, the Graphical User Inferface GUI is loaded and you are presented with the login screen. This was a very high-level overview of the boot process. If you're interested in Operating Systems, I would recommend that you read more on osdev.
It provides many helper functions that allow reading boot sectors of attached storage and printing things on screen. It does the same job as a BIOS, but with one basic difference: it stores all data about initialization and startup in an. This ESP partition also contains the bootloader.
UEFI takes these limitations into account and provides a Legacy mode. In it you can run everything as if you had a BIOS firmware.
